FEED-ROLLER ATTACHMENT FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 669,370, dated March 5,1901.

Application filed October 5, 1900. Serial No. 32,134. (No model.)

To aZZ whom, it mag concern.-

Be it known that I, JOSEPH E. PHILLIPS, a citizen of the United States,residing at Carlisle, in the county of Cumberland and State ofPennsylvania, have invented aoertain new and useful Feed-RollerAttachment for Spinning-Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to feed-roller attachments for spinning-machines,one of the principal objects of the invention being to provide afeed-roller device which may be substituted in a moments time for theordinary feed-roller at present in use.

A further object of the invention is to reduce to a minimum theliability of the breakage of the cords or threads adjacent to the feedand driving rollers, also to secure greater uniformity in the .twist ofthe thread.

A further and very important object of the invention is to facilitatethe threading or reeving of the thread around the feed and drivingrollers, thereby enabling an attendant in case the thread breaks toquickly detach the feedrollers, wrap the thread around such rollers, andreplace the rollers in the machine.

The detailed objects and advantages of the invention will appear morefully in the course of the ensuing description.

The invention consists in certain novel features and details ofconstruction and arrangement of parts, as hereinafter fully described,illustrated in the drawings, and incorporated in the claims.

In the accompanying drawings, Figure 1 is a diagrammatic section througha sufficient portion of the frame of a spinning-machine to illustratethe application of the present improvements thereto and showing also theordinary stop mechanism. Fig. 2 is an enlarged detail perspective viewof the improved feed-rollers and yoke or hanger therefor, together withthe lever by which the feed-rollers are detachably supported. Fig. 3 isa vertical section taken longitudinally of Fig. 2. Fig. 4 is adiagrammatic view showing the manner of reeving the thread around thefeed and driving rollers. Fig. 5 is an end elevation of'the driving andfeed rollers, showing a difierent manner of reeving the thread aroundthe same. Fig. 6 is a detail section taken longitudinally of one of thefeed-rollers, showing the manner of lubricating the same.

Similar numerals of reference designate corresponding parts in all thefigures of the drawings.

While the drawings illustrate a considerable portion of aspinning-machine, this invention appertains particularly to thefeeding-rollers, and it will not therefore be necessary to go into adetailed description of the spinning-machine itself, said machine beingof well-known construction, the thread 1 being taken from a series ofspools 2 and carried around the feed and driving rollers to the usualcop, (indicated at 3.)

l designates a lever having one end forked and the arms of the forkprovided with open sockets to receive the supporting-trunnions of theyoke or hanger, hereinafter described.

In carrying out the present invention I employ a pair of feed-rollers 6and 7, 6 designating the inner roller, which is provided with aplurality of circumferential grooves 8, and 7 designating the outerroller, which is provided with a single groove 9. The number of grooves8 and 9 in the rollers 6 and 7 may be increased or diminished at willwithout departing from this invention.

The feed-rollers 6 and 7 are journaled in a a yoke or hanger whichcomprises a body portion or web 10, lying wholly between the rollers andhaving its upper surface transversely rounded to permit the thread toslide freely thereover, said web being provided withoppositely-projecting pairs of arms 11, which carry the spindles orjournals 12, upon which the feed-rollers turn. If preferred, the rollersmaybe provided with trunnions journaled in the extremities of the arms11. The arms 11 project from the body or web 10 in opposite directionsand preferably incline slightly downward, as illustrated in thedrawings, and all of the arms are preferably made integral with the body10 and rigid with relation to each other and to the body or web. Theyoke or hanger is further provided with oppositelyprojecting trunnions13, forming extensions of the body 10, said trunnions being detachablyreceived in open sockets 14 in the forked end of the lever 4, as clearlyillustrated in Figs. 1, 2, and 3. The lever 4 is fulcrumed at in abracket 16, mounted on the frame I of the spinning-machine, and isassociated with the usual stop device. The feed-rollers 6 and 7 restagainst the driving-roller 5 and are actuated thereby until the threadbreaks, whereupon the lever 4 is vibrated, throwing the feed-rollers outof contact with the driving-roller in the manner and for the purposewell understood by those familiar with the art to which this inventionappertains.

From the foregoing description it will be seen that the improvedattachment, consisting of the yoke or hanger and feed-rollers carriedthereby, may be substituted quickly for the single feedroller at presentin use, the trunnions 13 resting in the sockets 14 of the lever at andbeing held therein by the weight of the yoke or hanger and thefeed-rollers. In the event of the thread breaking the attendant simplylifts the attachment, disengaging it from the lever, and then drawingdownward the thread 1 wraps said thread partially around the innerroller 6, thence outward partially around the roller 7, thence backpartially around the inner roller, and thence downward partially aroundthe driving-roller 5, after which the yoke or hanger is replaced in itscorrect position in the lever, whereupon the machine is ready to beagain thrown into operation. By providing the grooves 8 and 9 in thefeed-rollers the thread is prevented from coming in contact and chafingwhere it crosses, thus reducing to a minimum the liability of suchthread to break.

Instead of reeving the thread around the feed-rollers, as hereinabovedescribed and illustrated in Fig. 3, the thread may pass first partiallyaround the outside of the outer feedroller, as shown in Fig. 5, thenceunder both feed-rollers, partially around the inner feedroller, thenceover both feed -rollers, partially around the outer feed roller, andthence straight downward to the cop. To properly accomplish this, thefeed-rollers should be set fart-her inward, so as to enable the thread 1after leaving the outer feed-roller to pass straight downward to the cop3. Under the arrangement last described the outer feedroller will havethe two grooves and the inner feed-roller the single groove, or the re-Verse of the arrangement shown in Fig. 2.

The spindle or journal 12 of each feed-roller is preferably made ofbrass or other metallic tubing 17, as shown in Fig. 6, the ends of the.

tubular spindle being plugged, as shown at 18, and the tube beingpartially or wholly filled with wicking or other absorbent materialwhich will hold and gradually give out a supply of oil orotherlubricant, the lubricating material escaping through ports orperforations in the tubular spindles, as clearly shown in Fig. 6, andsupplying the necessary lubricant to the journal of the roller. Oil issupplied to the spindle by removing one of the plugs 18. The rollers arethus kept constantly lubricated without attention. Parts of the machinenot hereinabove particularly described may be constructed and arrangedin any ordinary or preferred manner.

Having thus described the invention, what is claimed as new, and desiredto be-secured by Letters Patent, is-

1. A yoke or hanger comprising a central Web, rigid arms projectinglaterally and in opposite directions from each end thereof, journalingtrunnions projecting from both ends of the web, and rollers arranged onopposite sides of the web and each having both of its ends supported bysaid arms, in combination with a support for the yoke or hanger, saidsupport having sockets with closed bottoms adapted to detachably receivethe trunnions of the yoke or hanger.

2. The combination with a lever having oppositely-arranged sockets, of ayoke or hanger comprising a central Web, rigid arms projecting laterallyand in opposite directions from each end thereof, supporting-trunnionsprojecting from both ends of the web and re movably fitted in saidsockets in the lever, and grooved rollers arranged on opposite sides ofthe web and each having both of its ends supported by said arms,substantially as described.

3. The combination with a lever having a forked end, the arms of whichare provided with open sockets, of a plurality of feed-rollers, and apivotal yoke or hanger in which the feed-rollers are journaled, saidyoke or hanger being detachably supported and journaled at both ends inthe sockets of the lever, substantially as described.

4. The combination with the driving-roll of a spinning-machine,of alever having a forked end the arms'of which are provided with opensockets located over the driving-roll, of a plurality of feed-rollers,and a pivotal yoke or hanger supported at both ends by the lever andhaving the feed-rollers journaled therein, said yoke or hanger beingprovided with trunnions journaled and detachably fitted in the socketsof the lever, substantially as specified.

5. A plurality of feed-rollers in combina tion with a pivotal yoke orhanger provided with oppositely-projecting pairs of rigid arms in whichthe feed-rollers are journaled and supported at both ends, and anintervening web or body portion lying wholly between the feedrollers andhaving its upper surface transversely rounded, said web being providedwith trunnions at both extremities for the support of the yoke orhanger, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
